**Assertion(A):** Electric and gravitational fields are acting along same line. When proton and \(\alpha\) - particle are projected up veritically along that line, the time of flights is less for proton.
**Reason (R):** In the given electric field acceleration of a charged particle is directly proportional to specific charge
